> IMO none of these questions should be asked in an interview, if you're hiring a new developer - and probably as a developer I would raise my eyebrow and asking myself silently "are you kidding me?". None of these questions guarantee that someone is actually a good developer. Interview questions should rather be about coding patterns or problem solving questions on a higher level. The language to do that is just a tool. Or ask which language you would use to solve a specific issue and why, because obviously not every language suites every use-case.
